Real estate broker Movoto has created a calculator that figures out how many Lego Bricks are needed to create a house.

Let’s get it out of the way for the information starved. A two-story house that is 2,169 square feet — the median size of a house, according to the Census Bureau–would take 10,079,829 LEGOs to build.

There’s a disclaimer here: Our estimate would be for the exterior of the structure, including the roof. So if you have have plans for things like interior walls, you’ll be adding more of the plastic blocks to your count. But once you get over ten million LEGOs, what does a few hundred thousand more matter?

That house would cost a little over $1 million in Lego Bricks alone, and as it said, that would just be for the external structure. Hardly seems worth it.
